Vented} certain new -.and useful Improvements in Car-Couplers, of which the following'is a specification.

. This invention relates to car couplers and has particular reference to means for taking up the slack between the knuckle of one coupler and the head of another coupler.

My invention is particularly adapted to light couplers which are used for connecting street,. elevated and subway cars where it is railroad cars.

the custom to allow the draw bar greater for by the M.- C. B. requirements for steam The result of such loose coupling is that in pushing cars or in operating trains of four or more cars there is considerable buckling and jerking, because of the flexibility of the coupling members. That is particularly true where long trains of five to eight cars are operated by unit control, that is, there being a motor in each car and all the cars being controlled by an operator in the forward car.

To overcome the above named difficulties I have devised the invention shown in the accompanying drawings of which;

Figure l'is a plan view of two couplers each equipped with my device; Fig. 2 is an end view showing the device applied to one knuckle; Fig. 8 is a side'elevation thereof; while Figs. 4, 5 and 6 illustrate a modification of the form shown in Fig. 1. i

i In the drawings, ,7, is the coupler head; 8, the guard arm thereof; 9 theknuckle; 10

the knuckle pin; and 11 the lifting pin. Inasmuch as the two heads shown in Fig. 1 are identical, I have deemed it necessary to describe but one thereof. 12 is the take-up device formed preferably ofa single piece.

of metal and polygonal in cross section, one side thereof being flared and fitting snugly Within a dovetailed groove, 13, formed Specification of Letters Patent.

Application filed July 21, 1908.

Patented Nov. 28,1911. Serial No. 444,629.

The vertical dovetailed groove, 13, int-he knuckle is terminated at a point abovethe lower face of the knuckle whereby, to provide a supporting seat for the takeup pin, preventing the same from dropping out throughthe bottom of the groove. This is a desirable and convenient construction, but

to those skilled in the art itv will be readily This apparent thatthe attachment of the pin to 7 the knuckle may be obtained in a variety-of ways, the pin'being held in place by any convenient means.

The form shown in Figs. 4, 5 and 6 is similar to that shown in Figs. 1, 2an'd3, except that there is no slot formed in the knuckle. The pin, 15, is suspended from the coupler when not in use, by means of a chain, 16. This form is adapted to be applied to any coupler now in use without the necessity for a special dovetailed. slot, as shown in Fig. 1. Upon the face of the pin, 15, I provide corrugations, 17,'to prevent the creeping of the pin in service. These teeth or corrugations are also placed on the back of pin 12, although in this particular. embodiment of the device there is :less likeli- As will be seen the couplers may be brought together and the coupling operation performed after which the pins may be dropped in place, or the pins may be first placed and the coupling operation follow, thus "taking up any slack which may have existed between the two parts. In, some cases it may be feasible or desirable to make the pin of wedge form so that it may be placed in the opening.

As various modifications ofmy invention will readily suggest themselves to one skilled in the art, I do not limit the invention to the specific constructions herein shown and described] Having thus described my invention, I pler head interlocked therewith, the bottom claim as new and desire to secure by Letters of said groove forming a supporting seat for Patent: said pin.
